February 9 is just eight days after the current scheduled release date for Wayne's continuously delayed Rebirth album. Today, another notable track from that album leaked.

For years now, Wayne has talked about how badly he wants to work with Eminem. Both rappers had verses on Drake's "Forever", but the first full-on collaboration between Wayne and Em surfaced today. According to MTV, the track, "Drop the World", will appear on Rebirth. And surprise! Both Em and Wayne sing on this thing. But they both rap, too. Don't worry.

The track starts out like most of Wayne's recent druggy, synth-drenched rock experiments, but the usual maelstrom of guitars subsides long enough for Wayne to deliver a couple of seriously heated verses. Eventually, Em comes in with a tricky, halting delivery that gradually builds into a hoarse scream. Of note: Both guys talk about how sad and angry they are. Exactly the sort of thing we want to hear from gazillioinaire rappers! Stream the song below, or hit up Nah Right for the mp3.
